The best Snail collars, compared.
Top pick: HanYun 12 pack plastic slug collars – Highest score: twelve PET rings at about £12.99, a stated 45° lip, and 21 cm by 12 cm lines that agree, with 4.9 from seven reviews. Best value: 25 felt cabbage collars, 15 cm – About £6.99 for 25 felt discs at 15 cm, with 4.4 from 52 reviews. The cheaper pack at about £3.59 has no reviews. Updated October 2026.
A snail collar is a barrier you seat around one plant. In UK shops it is either a raised open-top plastic ring with a downward lip, pushed into the soil around a seedling, or a flat felt or polyethylene disc laid around a brassica stem. You buy one to keep slugs and snails off lettuce, cabbage, beans, and flowers without metaldehyde pellets, illegal to sell and use outdoors since 1 April 2022. A raised ring is a climbing barrier for leaf-eating slugs and snails. A flat disc follows the cabbage root fly method, about 8–15 cm across, and the two jobs are not the same product. Where a depth is stated it is 2–3 cm, with no gap at the soil and no leaf bridging the rim. Prefer one size that the title, the bullets, and the technical line all repeat. A Wisley barrier trial did not support eggshells, grit, wool pellets, bark, or copper tape, and it did not test these plastic lip packs. How ring and disc differ is in the [snail collar buying guide](/hub/pest-control/snail-collar/sub/snail-collar-buying-guide).

Personal buying guide
Question 1 of 2
What are you covering?
The HanYun pack is twelve green PET rings at £12.99, each stated as 21 cm across and 12 cm high, with a 45° downward lip you push into the soil. On amazon.co.uk the line is 4.9 from seven reviews. UK reviewers describe the lip and the buried base stopping a climb, and water staying beside the plant, including in a grow bag. One set arrived too late for a full season of use. A wide plant is harder to thread, so fit the ring while the seedling is still narrow. The listing also names other crawling pests, while the reviews talk about slugs and watering. It is the top pick because the 21 cm by 12 cm lines agree and the lip is stated, and seven ratings still cannot show how the PET lasts.
Pros
Cons
Best for: You are covering a few seedlings or grow-bag plants and you want a raised lip whose size the listing states once.
Less suitable: You need a large UK review sample, or the plant is already wide enough to bridge the rim.
Specifications
Common questions
What are they made of?
The listing says PET, and describes it as semi-transparent. A separate material question on the page is not answered as its own line.
How are they fitted?
Push the collar into the soil and press soil around the edges. No tools are named.
What do the UK reviews add?
Reviewers describe the lip stopping a climb and water staying by the plant. One set arrived too late to use, and a wide plant is harder to fit.
Nogotizam is 25 black polyethylene discs at £4.09, stated as 15 cm across, and amazon.co.uk shows 4.5 from four reviews. A bullet also prints 20 x 17 x 0.14 cm, so the diameter is not the only size on the page. The only review text says they are good value and fit well around the plants, and it names no fault. The listing calls the design disposable and replaceable, and it claims less evaporation, which is not a measured saving. The title names nematodes and root fly; four stars and one short text do not test those jobs. At 80 g for the pack these are light sheets, and the listing does not state a slit or a lip. A 15 cm disc sits at the top of the RHS range of about 8–15 cm for a cabbage root fly collar, and it is still a stem cover rather than a wall a slug has to climb.
Pros
Cons
Best for: You want a cheap 15 cm polyethylene disc and you will check the fit on one stem first.
Less suitable: You need a raised ring for slugs on leaves, or a review that describes a failure.
Specifications
Common questions
What are they made of?
Polyethylene (PE). A bullet also calls the design disposable and replaceable.
Do they hold moisture?
The listing says they promote soil moisture retention and reduce evaporation. That is a claim, not a measured saving.
What does the review say?
The only review text says they are good value and fit well around the plants. It names no fault.
VETOLAKA is ten green rings at £10.99, and amazon.co.uk shows 4.5 from two reviews. The title says 23 cm. The technical line says 10 x 8 x 6 cm and 440 g, which reads as a packed size rather than a ring you can plan a bed around. The fit line is 2–3 cm into the ground, with a downward curved edge. The only written review is from Germany and says lettuces grew without slug grazing, so it is not UK opinion. The bullets also name aphids, butterflies, and ants, and nothing in the reviews supports those claims. Two ratings and a conflicting size are a thin basis at the same £10.99 as the McBlast ten-pack, which has 36 reviews.
Pros
Cons
Best for: You will measure the ring on arrival and you only need a small trial pack.
Less suitable: You need a UK review of this collar, or you are treating 23 cm as settled.
Specifications
Common questions
How wide is the ring?
The title says 23 cm. The technical line says 10 x 8 x 6 cm. Both are on the listing, so the size is unresolved.
How do you fit it?
Place it 2–3 cm deep and press the barrier into the ground. No tools are named.
Is there a UK review?
The star line is 4.5 from 2. The only written review is from Germany and says lettuces grew without slug grazing.
This unbranded pack is 25 black felt discs at £6.99, 15 cm across, with a cut to the centre so you can slide one around a stem. amazon.co.uk shows 4.4 from 52 reviews, the largest count in this comparison, which is why it is the best value beside the £3.59 Reyuvidep pack that has no reviews. UK buyers mention moisture at the base of cabbage and cauliflower. The same reviews say wind lifts the light discs unless you weight them or soak them, and one buyer found slugs sleeping underneath and says to check. Staples are optional and are not in the box. The listing says reusable for many years; a UK reviewer was unsure after the first year. One review is about carb counting and does not describe the collar, so 52 is not 52 gardening reports. This is a flat stem disc for a root-fly style cover, not a raised ring, and a slug eating leaves is a different job.
Pros
Cons
Best for: You are covering brassica stems with a felt disc and you will weight or soak the collars.
Less suitable: You need a climbing barrier for lettuce leaves, or you will leave light discs unweighted in a windy bed.
Specifications
Common questions
What are they made of?
Felt cloth, black, 15 cm across, with a cut to the centre.
Are they reusable?
The listing says reusable for many years. A UK reviewer was unsure after the first year.
What problems show up in reviews?
Wind blew the light discs off unless they were weighted or soaked. One buyer found slugs sleeping underneath and says to check. One review is about carb counting and does not describe the collar.
KAHEIGN is twelve green PET collars at £12.99 with a stated 45° downward lip, and amazon.co.uk shows 4.4 from 32 reviews. The size is not one figure: the title says 20 cm by 12 cm, a bullet says a 26 cm side and 12 cm height, and the technical line says 15 x 10 x 20 cm. UK reviews say cabbage seedlings and wallflowers were not eaten. One parcel contained 11 pieces, not 12. One buyer doubted the lip and planned to add copper mesh. The bullet tells you to press soil or stones around the ring so it does not blow away. Durability past one season is questioned in the reviews and is not measured. At 860 g the pack is heavier than the McBlast ten-pack at 380 g, and that weight still does not say which of the three sizes will arrive.
Pros
Cons
Best for: You want a lip ring with a mid-size UK review count and you will measure the ring when it arrives.
Less suitable: You need one agreed diameter before you order, or you are counting on a full twelve in every parcel.
Specifications
Common questions
What size is the collar?
The listing disagrees with itself: the title says 20 cm by 12 cm, a bullet says a 26 cm side and 12 cm height, and the technical line says 15 x 10 x 20 cm.
Will it blow away?
The bullet says to press soil or stones around it so it does not blow away.
What did UK buyers report?
Cabbage seedlings and wallflowers were not eaten in several reviews. One parcel contained 11 pieces, not 12, and one buyer plans to add copper mesh.
McBlast is ten green plastic rings at £10.99, model SG25-010-085, and amazon.co.uk shows 4.1 from 36 reviews, the largest raised-ring review count in this comparison. The product line prints 35 x 35 x 14.5 cm, and the diameter of one ring is not stated. Several UK reviews report less damage on sunflowers, marrows, runner beans, and lettuce. One UK buyer said slugs climbed the side and ate the cabbages. A Vine review says the ring can shift in loose soil. Other buyers added copper tape or copper mesh; the RHS Wisley trial did not find less lettuce damage from copper tape, and it did not test this pack. The bullets say the open top directs water to the root zone. A French review of this shape mentions heat at the base of strawberries or lettuce, which is not in the UK reviews.
Pros
Cons
Best for: You want the biggest UK review sample on a raised ring and you will check the soil seal the next morning.
Less suitable: You need a stated diameter before you buy, or you are protecting cabbages after a climb has already been reported.
Specifications
Common questions
Are they for outdoor plants?
The bullets name allotments, patio pots, and raised beds. The question on the listing is not answered as its own line.
Do they come in other colours?
The title and bullets say green. No other colour is listed.
Did every UK review say they worked?
Several UK reviews report less damage on sunflowers, marrows, beans, and lettuce. One says slugs climbed the side and ate the cabbages.
AOOWU is a 24-piece PET pack at £23.99, about £1 a ring, and amazon.co.uk shows 4.0 from 35 reviews. The listing gives the parcel as 27.9 x 24.8 x 22 cm and does not state the diameter or height of one ring. The bullet says to bury the collar 2–3 cm and press it hard so the wind does not take it. UK reviews include no slug damage on lettuce and on young hedge plants. One buyer returned the pack as thin, flimsy, and damaged. Another pinned the rings against high winds. At 1.13 kg it is the heaviest carton in this comparison, which does not tell you the wall thickness of a single collar. It covers the most plants in one raised-ring purchase, and it is also the pack a UK reviewer sent back.
Pros
Cons
Best for: You have many seedlings and you will check wall thickness and the count when the box arrives.
Less suitable: You need a stated diameter, or you want a lower price per ring.
Specifications
Common questions
How big is one collar?
The listing gives package dimensions only, 27.9 x 24.8 x 22 cm. The diameter and height of one ring are not stated.
How deep should it sit?
The bullet says 2–3 cm into the ground, pressed hard so wind does not take it.
What went wrong in UK reviews?
One buyer returned them as thin, flimsy, and damaged. Another pinned them against high winds. Others report no slug damage on lettuce or young hedge plants.
Ghligna lists twenty green PET rings at £15.99, with an outer diameter of 23 cm, a height of 11.5 cm, a 15 cm base, and a 3 cm lip at 45°. The fit line says press 2–3 cm into soil or mulch, with no stakes. amazon.co.uk has no star line and no review text, so the score stays at 40. The listing says the open top directs water and liquid fertiliser to the roots, and it names caterpillars, with no buyer report behind either line. Questions on the page about how long the PET lasts, use in pots, and whether the rings stack are asked and left unanswered. At 940 g for twenty pieces the spec is fuller than the other unreviewed packs, and there is still no review of it in use.
Pros
Cons
Best for: You want a written 23 cm ring spec and you can judge the first plants yourself.
Less suitable: You are choosing from UK reviews, or you need a buyer report on thin walls.
Specifications
Common questions
How long does the PET last?
The listing asks this and does not answer it. No lifespan is stated.
Can they be used in pots?
The question is on the listing and is not answered. The fit line says soil or mulch.
Do they stack for storage?
The listing asks and does not say.
Bettsolt is 25 felt discs at £8.99, with a stated outer diameter of 27 cm (10.6 inches) and a pre-cut seam you slide around the stem. The listing has no star line and no review text, so the score stays at 36. The RHS cabbage root fly collar is a flat disc of about 8–15 cm; 27 cm is wider than that note, and these discs were not in an RHS trial. The bullets claim breathable felt, drainage, root flies, nematodes, and weeds, with no buyer report. A technical line of 15 x 8 x 1.5 cm sits beside the stated 27 cm outer diameter. This is a flat stem disc, so it does not give you a climbing lip. At 250 g for 25 pieces you are paying £8.99 for a wide disc that no review describes in use.
Pros
Cons
Best for: You want a wide felt disc for a brassica stem and you accept an unreviewed listing.
Less suitable: You need a raised lip for leaf-eating slugs, or you want the RHS 8–15 cm size with UK reviews.
Specifications
Common questions
What are they made of?
Felt cloth. The listing says that allows air and water through.
How do they go on?
Slide the pre-cut seam around the stem and centre the hole. No tool is named.
Is there a star rating?
The listing has no customer-review line and no review text.
Reyuvidep is the cheapest pack in this comparison, 25 discs at £3.59, stated as 15 cm across and 0.1 cm thick, at 18 g. The material is not named. amazon.co.uk has no star line and no review text, which is why the score stays at 28 and why this price is not the best value. The bullets claim soil hydration, root fly, and nematodes, and the page asks about installation, plants, and weather without answering. A 15 cm disc sits at the top of the RHS range of about 8–15 cm for a cabbage root fly collar, and these discs are not a named RHS product. With no fit method and no material, you cannot tell whether the sheet is felt, plastic, or something that will tear. Best Sellers Rank 95 in Slug & Snail Control is a shop position, not a review.
Pros
Cons
Best for: You want the lowest shelf price for a 15 cm disc and you can try a pack that no review describes in use.
Less suitable: You want a named material, a UK review, or a raised lip.
Specifications
Common questions
Are they easy to install?
The listing asks this and does not answer it. No tool is named, and no fit method is stated.
Which plants are they for?
The question is unanswered. The bullets say flower beds and vegetable patches.
Will they cope with weather?
The listing asks and does not say. There is no review text.
Ten amazon.co.uk listings are scored from the star line, whether a lip is stated, and whether the size lines on that listing agree. There is no laboratory trial and no Royal Horticultural Society test of these packs. A flat disc is scored as a different job, not as a failed ring. The top pick is the highest score. Best value is pack price set against the review count. A size conflict, a missing piece size, a written review from outside the UK, a UK report of a climb or a short count, and wind lift on a disc are marked down. A listing with no star line is capped.
Stars and review count
35%amazon.co.uk stars count only with the number of ratings on that listing. A high star line on a handful of ratings does not outrank a consistent size plus a clear lip. A listing with no star line is capped.
Lip and size agreement
30%Points follow a stated lip or slit, and one size that the title, the bullets, and the technical line repeat. A missing piece size, or three sizes that disagree, does not receive the size point.
Review content
20%Points come off for a UK report of a climb or a short pack, wind lift on a disc, and a written review that is not from the UK. A flat disc is not treated as a failed ring.
Price against the review count
15%Shelf price is the amazon.co.uk figure captured for that listing. Best value is price set against the review count. The cheapest pack, with no reviews, does not take that place.
Start with the job, then the seal, then one size the listing repeats. A raised ring is a climbing barrier for leaf-eating slugs and snails. A flat disc is a stem cover for cabbage root fly. The two names are not interchangeable. Shelf prices captured here run from about £3.59 to about £23.99. Nothing on this page is a laboratory count of plants saved, and the RHS did not test these packs.
A snail collar in UK shops is one of two products. A raised open-top plastic or PET ring has a downward lip and is pushed into the soil around one seedling, so a slug or snail has to climb a wall. A flat felt or polyethylene disc is laid around a brassica stem, with a slit to the centre. Gardeners buy them for lettuce, cabbage, beans, and flowers when they do not want metaldehyde pellets. Those pellets have been illegal to sell and use outdoors since 1 April 2022.
A 15 cm disc does not stop a slug eating leaves, and a lip ring does not follow the cabbage root fly method at the stem. The RHS collar note is a flat disc of about 8–15 cm. Treat the names as different jobs.
A wide plant is hard to thread, and a leaf or a runner can bridge the rim. Listings that state a depth say 2–3 cm. Thin plastic that bends, and discs that blow away, fail before the lip matters.
The Wisley trial did not find less lettuce damage from copper tape, and it did not test these plastic packs. A listing that names aphids, nematodes, or weeds is not evidence that the collar does that job.
Choose the shape for the damage you can see. A raised PET or plastic ring with a downward lip is for leaf-eating slugs and snails. A flat felt or polyethylene disc is for cabbage root fly at the stem. Packs of rings in this comparison run from 10 to 24 pieces. Flat discs are packs of 25, at 15 cm or 27 cm where a diameter is stated. Heights on rings, where stated, sit around 11–14 cm, and a lip is often described as 45 degrees. The open top is also sold as a watering funnel.
Prefer one measurement that the title, the bullets, and the technical line all repeat. Reject or down-rank a listing whose sizes disagree, or that only gives the parcel dimensions. A 15 cm disc sits at the top of the RHS range of about 8–15 cm. A 27 cm disc is wider than that note. After the size is readable, match the pack count to the number of plants, then the price. Captured shelf prices put 25-disc packs under £9 and raised rings from about £10.99 to £23.99.
Three typical situations, each with a recommendation from this comparison.
You want a non-pellet shield for a few seedlings and you will check the ring the next morning. The HanYun 12-pack at about £12.99 is twelve PET rings stated as 21 cm by 12 cm, with a 45° lip, and 4.9 from 7 reviews. UK reviews describe the lip and water staying by the plant. Seven ratings cannot show how the PET lasts. Skip it if the plant is already wide enough to bridge the rim.
You need a flat disc for cabbage root fly at the stem, not a climbing wall. The unbranded pack is 25 black felt discs at about £6.99, 15 cm across, with 4.4 from 52 reviews. That 15 cm sits at the top of the RHS range of about 8–15 cm. Wind lifts them unless you weight or soak them. Leave this pack if slugs are shredding leaves above the stem.
You are using a raised ring as a water well around a pot or a grow bag. HanYun reviews describe water staying beside the plant, including in a grow bag, at about £12.99 with a stated 45° lip. The open top is not a measured saving. A wide plant is harder to thread, so fit the ring while the seedling is still narrow.
The top pick is the HanYun 12-pack of plastic slug collars at about £12.99. It is the highest score: twelve PET rings, a stated 45° downward lip, and 21 cm by 12 cm lines that agree, with 4.9 from seven amazon.co.uk reviews. The sample is small, a wide plant is harder to fit, and one set arrived too late to use. The best value is the unbranded pack of 25 felt cabbage collars, 15 cm, at about £6.99, with 4.4 from 52 reviews, the largest count in this comparison. The price is set against that review count. The job is a stem disc, not a raised lip, and wind lifts the discs unless they are weighted or soaked. A cheaper 25-pack at about £3.59 has no reviews, so it does not take the best-value place. Neither result is a laboratory test, and a slug can still cross a gap or a leaf bridge.
